located at the top, ends, or sides of the car.

The primary object of my invention is the combination, with the car-body and the trucks,

of an ice-receptacle placed beneath the carbody and interposed between the two trucks. By this arrangement great economy of room is secured, and the weight of thefreezingmixture is placed at thelowest possible point, so as to produce greater steadiness in the running of the car andlesswear, and so as to re] quire less strength in the construction of the body of the car.

Figure 1 represents a longitudinal section 'taken through the center of I the car, Fig. 2 represents a transverse section taken through the middle of the car. 1

A is the space in the car in which are placed the substances to be refrigerated upon books or shelves or other suitable supports.

B is a pipe or conduit with perforations, as shown, which runs preferably along the roof of the car, and thence extends downward at one end and along under the floor until it The arrangement of the pipe 3 whichI have shown I deem to be preferable; but any other arrangement may be employed which would take the air from the car-body at any desired point or points and convey it to the fan C.

D is a box suspended from the timbers of the body of the car intermediate the .two

trucks. This box incloses the apparatus for holding the ice and conveying the air into proximity to it for the purpose of being cooled, The exit for'the air from the fanblowef connects-with one end of this box and with a pipe, E, which runs from one end of end of the box opposite to the fan-blower the pipe E empties into a vertical passage, F,

A above this chamber G is perforated, so that the air is distributed in escaping from. the chamberG into the compartment A, as indi-v cated by the arrows. The pipe E is preferably oblong in cross-section, as shown in Fig;

2, and the top of this pipe, which forms the resting place for theice, is supported on stays or trusses e, so as to secure thestrength necessary for sustaining the weight of the ice.

. H is the compartment where the ice is placed through the doors h h, one on each side of the ice-box. This compartment H extends over the pipe E and down at its ends, as at h h, Fig. 2. When the ice-boxis charged, the ice will extendover t-he top of the pipe eand down around its ends, as at h h,- but the space l, below thev pipe E, is preferably madeof'such" "1 a limited vertical height that the ice will not enter it, but sothat it will be entered by the meltings from the ice, which finally escape through a trap, as at m. I

n is an air-space at the endof the ice-cham- 'ber,-which will serveto isolate it from-the outside atmosphere. g 1 The fan 0 is preferably placed and sus-' pendednearly on a level with the axle of the car, as shown, so that comparatively slight strain is brought to bear upon the belt I by 8 the motions of the car. Whatever variations occur in the tension of this belt will be taken up by the idler-pulley K. Thepower for driving the belt Jr is obtained from a'pulley secured to the axle ofthe car. 3 The size and form of the-pipe E and the relationship between it and the ice-compartment H will be regulated as circumstances require; but I prefer a form of pipe E oblong in crosssection, like that shown in the drawings, because of the fact that a greater surface of air. is presented to the cooling-surfaces of the pipe in passing through. The space 1 below' the pipe Eis also preferred to be low, so that the drippings of the icevor ice and salt will be brought intimately unto contact with the bot-. tom of the pipe E, and thus themselves will serveas an additional cooling agent. When the car is running, the rotation of the v fan Owill draw the air intothe perforationsof the pipe Eat the top of the car, where the air is warmest, and down to the eye of the fan. From the fan the air is forced through the pipe E, where it is brought in contact with the coolingof the car.
